Abstract
The utility model discloses a teaching device, and especially discloses a physical dynamic overweight and weightlessness demonstration device. The physical dynamic overweight and weightlessness demonstration device comprises a pressure transducer, a wireless supervising device, a display screen, pulleys and a support. The lower end of the support is provided with a pedestal. The left side and the right side of the upper end of the support are respectively provided with the pulleys. The support below the pulleys on the two sides is provided with the display screen. The left side of the support is provided with a guide rod. The guide rod is provided with a lifting platform. The pressure sensor is arranged inside the lifting platform. The upper end side of the pressure sensor is provided with the wireless monitoring device. The pressure sensor is connected to the pulleys through a rope. The tail end of the rope is provided with a counterweight block. The beneficial effects of the physical dynamic overweight and weightlessness demonstration device are that: the physical dynamic overweight and weightlessness demonstration device is simple in structure, easy to use, and relatively small in size and resembles what students feel in life. The problem in the prior art that the pressure numeric can not be concretely read when an object is in motion is solved. The physical dynamic overweight and weightlessness demonstration device is very persuasive and can demonstrate overweight and weightlessness dynamic states under various conditions in a very convenient, visual, and timely manner.
Description
Technical field
The utility model relates to a kind of instruments used for education, particularly the dynamic Overweight and Zero Gravity demonstration device of a kind of physics.
Background technology
Overweight, weightlessness is the difficult point of senior middle school physics teaching, it also is the important phenomenon in the present science and technology of aviation, traditional demonstration device is many to come qualitative demonstration with deformation, very big with student's life feeling difference, effect is very bad, do not have cogency, novel super, the weightless demonstration device of this paper design can come out the dynamic demonstration in good time of the Overweight and Zero Gravity under the various situations intuitively.
The utility model content
The utility model provides a kind of simple in structure in order to remedy the defective of prior art, the convenient dynamic Overweight and Zero Gravity demonstration device of physics that uses.
The utility model is achieved by the following technical solution:
The dynamic Overweight and Zero Gravity demonstration device of a kind of physics, comprise pressure transducer, wireless monitoring device, display screen, pulley and support, base is equipped with in described support lower end, and the left and right sides, support upper end is equipped with pulley respectively, on the support of both sides pulley downside display screen is housed, guide rod is equipped with in the support left side, lifting table is housed on the guide rod, pressure transducer is housed in the lifting table, the pressure transducer upside is equipped with wireless monitoring device, be connected by rope between pressure transducer and the pulley, rope end is equipped with balancing weight.
The beneficial effects of the utility model are: simple in structure, easy to use, volume is less, approach with student's life feeling, solve original object and can't specifically read the problem of pressure value at the volley, have stronger cogency, come out the dynamic demonstration in good time of the Overweight and Zero Gravity under the various situations intuitively in the aspect very much.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the structural representation of the dynamic Overweight and Zero Gravity demonstration device of the utility model physics
Among the figure, 1 base, 2 supports, 3 pulleys, 4 guide rods, 5 ropes, 6 lifting tables, 7 pressure transducers, 8 wireless monitoring devices, 9 balancing weights, 10 display screens.
Embodiment
Accompanying drawing 1 is a kind of specific embodiment of the present utility model.The dynamic Overweight and Zero Gravity demonstration device of a kind of physics of this utility model, comprise pressure transducer 7, wireless monitoring device 8, display screen 10, pulley 3 and support 2, base 1 is equipped with in described support 2 lower ends, the left and right sides, support 2 upper end is equipped with pulley 3 respectively, on the support 2 of both sides pulley 3 downsides display screen 10 is housed, guide rod 4 is equipped with in support 2 left sides, lifting table 6 is housed on the guide rod 4, pressure transducer 7 is housed in the lifting table 6, pressure transducer 7 upsides are equipped with wireless monitoring device 8, be connected by rope 5 between pressure transducer 7 and the pulley 3, rope 5 ends are equipped with balancing weight 9.The dynamic Overweight and Zero Gravity demonstration device of a kind of physics of this utility model, changing balancing weight 9 sizes during use can make lifting table 6 accelerate to rise, accelerate to descend, lifting table 6 decelerations were risen after the length of change rope 5 can make balancing weight 9 land, the apparent weight of object is measured with electronic scale in the motion, and its numerical value is shown by the display screen 10 that wireless monitoring device 8 recorded and be sent to support 2 tops in good time.
